every now and then, when i put my foot down from low revs in low gears(1&2) i get a second or so of nothingness. It feels a bit like turbo lag but i dont have a turbo. Its really strange, any ideas? its a 1800CC BLOCK BORED TO 1900CC, FAST ROAD CAM, RACE PISTONS, ENLARGED THROTTLE BODY, BIGGER WARM-UP VALVE, ENLARGED OIL SUMP, HIGH PRESSURE FUEL PUMP, POWER CLUTCH (copy and paste, hence the caps). thanks.
